Trimble SPS855 GNSS Modular Receiver

The Trimble® SPS855 GNSS Modular Receiver is simply the most advanced construction modular receiver on the market. Its position-only or position and heading capability set it apart from the competition. Its ease of configuration and use as a base or rover, and its choice of antennas make it truly universal - capable of any operation.

The SPS855 combines the radio and GPS receiver in a single housing. You can secure the majority of your investment inside a site trailer, vessel cabin, or carrying case, protected from the elements and/or theft, leaving only the antennas outside.

Available in a range of options to suit your individual applications, flexibility and performance requirements, versatile Trimble GNSS receivers are a future-proof investment. The SPS855 uses all currently available satellite signals including L1, L2 and the GPS modernized L2C code. It can be upgraded with GLONASS and L5 GPS signals to optimize performance in areas of tough GPS-only conditions and maximize your investment well into the future.

It is also part of a larger family of receivers that have the same user interface, the same accessories and the same workflows, allowing multi-unit fleets to be created with interchangeable components.

Features & Benefits of the Trimble SPS855 GNSS Modular Receiver

The SPS855 GNSS Modular Antenna delivers the flexibility, accuracy and performance you need for heavy civil and marine construction applications. This unit offers numerous features and benefits, including those listed below:

FeatureWhy it is important to you?
Modular design The SPS855 GNSS receiver is a combination of an integrated unit that contains the GNSS receiver, radio and radio antenna plus battery and an external GPS antenna. The choice of antenna allows the receiver to be used as a rover on a pole or backpack, as a base station with a Geodetic antenna, or on a machine or marine vessel using the rugged antenna.
Trimble xFill™ technology Available only in Trimble GNSS receivers, the optional Trimble xFill™ technology can expand site productivity by allowing short excursions into valleys and other locations where GNSS corrections were not previously available.
Security The receiver unit can be placed in a secure environment where it can be protected from theft and weather while the less expensive GNSS antenna can be placed in a location with clear visibility to the sky.
Power The long life internal battery will power the receiver in base operation (transmit data) for up to 10 hours using GNSS satellites. When the receiver is connected to mains power then it will use this as the primary power supply, should there be a mains outage then the internal battery will become active working like an Uninterrupted Power Supply and keep the site working.
Flexibility The SPS855 GNSS Receiver can be configured in a variety of locations -- on site cabins, site trailers, in vehicles, light machines or on marine vessels. Flexibility and configuration options make it usable for many applications on site, improving your return on investment.
Front panel display The receiver can be easily and quickly configured by the front panel display. All information on the status of the receiver is displayed -- mode, radio frequency, SVs tracked and whether the radio is transmitting. No need to set up a controller.
Internal radio No need for external radio and extra cables. Inbuilt radio for transmitting or receiving data.
Autobase function Stores the last 13 stations and allows starting the base with one button press.
GNSS With 440 channels, CMRx as well as the ability to track GPS, GLONASS, BeiDou and Galileo, the SPS855 receiver is a future-proofed investment in positioning technology.
Upgradable Upgrade the receiver to suit your changing needs. Purchase the receiver that you need today and upgrade to more satellite signals or higher accuracy when those needs change.
Connectivity The SPS855 can be connected to the Internet via an optional Trimble SNM940 Connected Site Gateway or a Connected Controller such as the Trimble Site Tablet or TSC3. Once connected, the receiver can receive corrections via Trimble Internet Base Station Service (IBSS) and can be accessed remotely using its IP address for monitoring and fault diagnosis.
WebUI Built in Web User Interface can be used to configure the receiver. Connect via Bluetooth from a PC or via the internet if the receiver is connected via the Ethernet connection.
Trimble IBSS base station capability When the SPS855 receiver is connected with the SNM940 cellular modem the SPS855 can work as an Internet Base Station. The SPS855 uses Connected Community to provide a correction stream to multiple internet-connected rovers. It removes the IT complexity, the hassles associated with private and dynamic IP addresses and the limited number of users associated with using NTRIP Caster function.
SPS555H Heading Add On Receiver The SPS855 can be combined with an SPS555H Heading add on receiver to provide both precise position and heading for applications on cranes, vessels and dredgers where the position and orientation in real-time is important.

Applications for the SPS855 GNSS Modular Receiver

The Trimble SPS855 Modular GPS Receiver is optimized for use as a permanent or semi-permanent base station to provide GNSS corrections for site measurements and machine control. It can also serve as a rover, moving easily from a site supervisor truck to a pole mount for grade checking, site measurement and stakeout.

The Trimble SPS555H Heading Add-on Receiver can be used with the SPS855 to supply precise position and heading for applications on cranes, vessels and dredgers where the position and orientation in real-time is important.

GNSS capability

Featuring the new Trimble Maxwell™ 6 chip, the Trimble SPS855 GNSS Modular Receiver advances the industry with more memory, more GNSS channels and the ability to track and provide corrections for up to 44 satellites. The ability to track more satellites means faster system initialization and improved operation near tree canopies or other obstructions. It can also mean reduced system downtime during periods when GPS satellite availability is limited.

The SPS855 supports the following satellite systems and correction sources:

  • GPS, GLONASS, Galileo and Compass
  • Satellite-based Augmentation Systems such as WAAS, EGNOS, MSAS, and QZSS
  • OmniSTAR™ VBS, XP or HP
  • Precision GNSS base station (RTK corrections)
  • DGPS using UHF radio links (RTCM)
  • Virtual Reference Station (VRS)
  • Trimble Internet Base Station Service (IBSS)
